Handballs have become increasingly problematic for Premier League referees, with Jose Mourinho lamenting Craig Pawson’s decision not to give Manchester United a penalty on Saturday against Southampton’s Maya Yoshida.

FA rules state a handball must be a “deliberate act” and the distance between the opponent and ball should also be considered.

Wenger said: “FA rules change always during the season because they must watch the television and say ‘oh, he has given penalty – maybe next time I do it as well’.

“They need a clear guidance. I personally think you have to make the rules as simple as possible.”
